CAR-JOURNAL-BOX LID.

Specification of Letters Patent.

Patented Nov. 27, 1906.

Application filed November 24, 1905. Serial No. 288,921.

vented new and useful Improvements in Ihead of the lid 13, the curvedexterior surl20, two lugs upon the sleeve, having curved Car-Journal-BoxLids, of which the following is a specification.

The invention relates to car journal-boxes, and especially to the meansfor closing the opening at the end thereof through which oil and wasteare introduced to theinterior of the box, the object being the provisionof a double cover or lid which shall prevent the entrance of dirt anddust to the bearings.

The invention consists in certain novelties of construction andcombinations of parts, as hereinafter set forth and claimed.

The accompanying drawings illustrate an example of the physicalembodiment of the invention constructed according to one of the bestmodes we have so far devised for the application of the principle.

Figure 1 is a side view of the box, partly in section at the end. Fig. 2is an end view in elevation. Fig. 3 is a vertical section. through thetwo lids, showing the said lids in open positions. Fig. 4 is ahorizontal section. ofFig. 1 in a plane parallel with the bolt. Fig. 5shows the sleeve and lugs. Figs. 6 and 7 show the lug 20 and the spring28.

Referring to the several figures, the numeral 1 designates the openingat the end of the box, through which oil and waste are introduced; 2, aninwardly-projecting flange bounding the opening 5 3, cam-shaped lugs, 4,holes through the lugs, 5, the projecting parts of the lugs g 6, aconcave surface at the top of the box and extending between the lugs; 7,the outer lid g 8, the flange of the outer lid; 9, the widened sides ofthe lid g 10, holes in the sides; 11, a bolt passed through the lugs andholes in the lid 5 12, the

face of the head of the lid located between the lugs, 14, the end wallsof the head of the lid, 15, the inner edge of the head; 16, a curvedleafsspring; 17, the convex surfaces at the ends of the spring 18, abolt passed through the spring and lid and which holds the spring at itscenter in contact with the lid through the medium of a nut 5 19, asleeve with a hole therethrough to fit the bolt 11;

outer surfaces; 20', a lug located upon the opposite side of the sleevefrom the two lugs 21, the innerlid, 22, a flange about the edge of thelid; 23, a recess in the metal, bounding the opening at the end of thebox within which the flange 22 is seated when the lid is closed; 24, twoarms secured to the lid, 25, holes in the projecting portions of thearms, said holes being in line with the lugs 20 of the `:sleeve asshown- 26 cam-surfaces of the l f 7 holes, each of which extends from ato b, as shown in the several sections, and 27 is a seat for the lug 20@which seat is located at the inner surface of the head of the cover.

In Figs. 6 and 7 is shown a spring 28, secured to the head of the outerlid and with its free end bearing against the lug 20 on the sleeve. Whenthe outer lid is being closed and approaches its seat, the spring bearsagainst the lug 20 and forces the inner lid to its seat, and when theouter lid is entirely closed the spring holds the said inner lid inconstant frictional contact with the inwardly-projecting flange 2,bounding the openingat the end of the box.

The relative location of the several parts when assembled is obviousfrom the drawings and need not be set forth in detail.

Upon reference to Fig. 1, which shows the lid closed, it will beobserved that the curved surface at the rear of the edge 15 of the headis in frictional contact with concave surface 6 between the lugs andthat dust and dirt cannot enter between the surfaces, that the exteriorsurfaces of the end walls 14 of the head are in frictional contact withthe inner surfaces of the lugs,.and that the flange 8 of the lid fitsaround the opening at the end of the box. There are thus no open spacesbetween the box and the lid. Further, it will be observed that thecurved surfaces of the free ends of the spring are in frictional contactwith the surfaces of the lugs directly in front of the projectingportions 5 thereof. The spring ends being under tension hold the lidclosed, so that the jarring of the box when the axle and wheels are inmotion will not allow the lid to leave its seat. The spring is locatedparallel with the bolt 11 and within a recess at the upper end of thelid and slightly curved, as shown, so that when the lid is opened theends of the spring may bend as the curved surfaces thereof travel overthe projecting portions 5 of the lugs. 1t will be seen that in closingthe -lid the ends of the spring will engage the cam-surfaces of the lugsand when they reach the lpositions shown in Fig. 4 that the lid will beheld closed with a force corresponding to the stiii'ness of thespring.

The inner lid 21 is operated simultaneously with the outer lid when thelatter is rotated. When the outer lid is o cned, the sleeve 19 movesrelative to the bo t l l, inasmuch as the lug 20 engages the seat 27 inthe head of the cover, and the lugs 2O move along the camsurfaces 26 26from b to a, where they stop, and further motion of the outerlid opensthe inner lid; as is clearly shown by Fig. 3 oi the drawings. In closingthe outer lid the lugs 20 move over the cam-surfaces 26 26 from av to b;and when the outer lid is seated the lugs '2O 20 hold the innerlid'fnmly and closely to its seat.

In the practical application of the principle of the inventionmodifications of course may be introduced which will not constitutesubstantial departures.

What we claim isi 1. The combination with a journal-box, of two lids; abolt; and a sleeve provided with lugs and located upon the said bolt;one oi' said lugs engaging the outer lid and another lug engaging theinner lid, whereby moveln ndent of the outer lid also operates the inner2. The combination with a journal-box, of two lids; a bolt; and sleeveon the bolt, said sleeve havinga 'plurality of lugs; one of said lugsengaging the outer lid, and the other lug or lugs locking the inner lidto its seat when closed.

3. The combination with a journal-box, of two lids; a bolt about whichsaid lids rotate; and a sleeve with lugs upon opposite sides thereof7said sleeve being located upon the bolt; one of said lugs engaging aseat in the outer lid; and the other lug or lugs adapted to operate theinner lid.

4. The combination with a j ournal-box, of two lids; a bolt; a sleeve onthe bolt, said sleeve being provided with` lugs; and means supported bythe sleeve which is adapted to be engaged by the outer lid.

5. The combination with a journal-box, ot' inner and outer lids; saidouter lid being provided with a spring for locking the same in closedposition, and said inner lid having arms with cam-surfaces a bolt; and asleeve with lugs located upon the bolt, one of said lugs engaging theouter lid, and the other lugs engaging the cam-surfaces of the arms, insubstance as set forth.

6. The combination with a journal-box having an opening at the end, ofhinged inner and outer lids, said outer lid having perforated i'langesat the sides; two perforated lugs at the edge of the opening at the endof the box; and a bolt passed through the perforations in the flanges ofthe outer lid and in the lugs; said lid being movable relative to thebolt.

7. The combination with a journal-box having an opening at the end, ofinner and outer lids, and means at the top edge of the box for hingingthe lids so each may move through the part of an arc oi' a circleindependently of the other, said means comprising perforated lugs and abolt; the outer lid being movable independently of the movement of thebolt. i

8. The combination with a journal-box having an opening at the end, oftwo lids hinged to the side of the opening; a lug with a cam-shapedsurface; and a spring engaging the cam-surface of the lug and inconnection with the said lids; said spring being actuated by the outerlid and serving to hold the inner lid to its seat when the outer lid isclosed.

Q. The combination in a journal-box having an opening at the end, of twolids; two perforated lugs at the edge of the opening; a bolt passedthrough the lugs; and means for hinging the edges of both lids to thebolt; said outer lid being movable independently oi the movement of thebolt. v l

l0. The combination with a journal-box having an opening at the end, oftwo lids, each lid being hinged and movable through the part of an arcof a circle independently of the other lid; means for hinging the lidsto the edge of the opening comprising perforated lugs and a bolt; andmeans for holding the outer lid closed; said outer lid being movableindependently of the bolt.

l1. The combination with a journal-box having an opening at the end, oftwo separate lids; a bolt and lugs at the upper edge of the said openingby which the lids are hinged; and means in connection with the inner lidadapted to be-engaged by the head of the outer lid when closed, wherebythe inner lid will be held to its seat.
